Nigel Pearson is surprised that Watford are embroiled in a battle for Premier League survival after presiding over their climb towards safety.

A rousing 2-1 victory over Wolves at Vicarage Road has left the Hornets just two points adrift of 17th place with a haul of 10 points from four games over the festive period offering hope of escaping relegation.

Since replacing Quique Sanchez Flores in early December, Pearson has lost just one of five matches and the head coach's only puzzlement is why the club have been struggling.

"Because of the types of performances the players have produced, what surprises me is why we've not been able to do it for more of the season," he said.

"With the players we have I'm surprised that we're in the condition we're in and the circumstances we're in.

"We've tried to keep things pretty simple and try to create an atmosphere in the club because we have maybe lost a little bit of our identity in terms of how we play.

"I've been trying to unite what we have because we've got good players and lots of good characters

"When teams are at the bottom there's always a suspicion there may be something else going on, but this is a good club with good people working for it, including the players.

"This club has character and we need to reflect that on the pitch, but there's a lot of hard work still to be done.

Pearson may be forced to bolster his resources in defence after Kiko Femenia limped off with a hamstring injury against Wolves, but new arrivals during the January transfer window are likely be kept to a minimum.

"We may do something because we have a few injuries at the moment. I'm not a believer in collecting players," Pearson said.

"If we can improve what we have then fine, but I've been very encouraged by the players that we have.

"We're rediscovering some form, which will be important for us. There might be some defensive cover, who knows.

"Kiko Femenia's hamstring injury...he's played so, so well for us... so we'll have to look at that. But we won't be adding lots and lots of players.

"We'll do what we think is right to give us a more realistic chance of retaining our Premier League status."
